After this first test Jan-Åke Malmqvist of Dellencat commented:
"Made a perfect sail today! I don't want to sail the old way any more!
I would have liked some more wind today but it was ok for the first test.
We have some things to change, but only minor.
For the first time ever sailing I felt that the boat was following my instruction.
 And there were no big side-forces when the boat or wind was changing direction.
 It was a great day!"
